Neurons in the eye turn light into electrical signals. How and where signals travel between these cells is thought to affect vision.
Scientists who study the brain do so for many reasons. For some, the opportunity to study the most complex living structure in the known universe is itself an exciting quest. So much is still unknown about brain function and development.

Optical imaging relies on shining weak lasers through the skull to visualize brain activity. These techniques are inexpensive and relatively portable. They are also silent and safe: Because only extremely weak lasers are used, these methods can be used to study everyone, even infants.

PET is one of the most important techniques for measuring blood flow or energy consumption in the brain. This method of measuring brain function is based on the detection of radioactivity emitted when positrons, positively charged particles, undergo radioactive decay in the brain.
